the men's service. they were killed in that attack in the u.s. embassy in benghazi. >> now, more on an attack that killed two american service members in air base. it a it's the same base where england's prince harry is stationed. reports say the prince was not hurt. nbc news chief pentagon correspondent joins us by phone. first, mitt, can you tell us more about what happened this in that attack? >> well, officials tell us that this was a complex attack. in other words, it went on for some time. very well organized. it involved small-arms fire, rocket fire and some mortar fire at camp bastion. now, tragically enough, two u.s. marines were killed in that attack by presumably th the taliban. but what drew world attention, of course, is this is where prince harry who just arrived on his second four-month tour for the british military is based there at camp bastion. now, what was odd about this is that when he arrived, the british military itself issued a press release and even video of harry there in an hipachee helicopter. now, in previous visits, there was no public announcement.
